Abstract
An efficient copper-catalyzed cascade difunctionalization of N-allyl anilines toward the synthesis of silylated indolines using commercially available silanes has been reported. This strategy provides a new avenue for the synthesis of a diverse array of indolines in reasonable yields. Preliminary mechanistic investigations indicate that the reaction probably proceeds via a radical pathway with unactivated alkenes as radical acceptors and simple silanes as radical precursors. This protocol is distinguished by its atom economy, broad substrate scope and readily available starting materials.

Abstract
A visible light-mediated heterogeneous photocatalytic cyanomethylarylation of alkenes with acetonitrile has been established using K-modified carbon nitride (CN-K) as a recyclable semiconductor photocatalyst. This protocol, employing readily accessible alkyl N-hydroxyphthalimide (NHPI) ester as a radical initiator, allows the efficient construction of a broad array of structural diverse nitrogenous heterocyclic compounds including indolines, oxindoles, isoquinolinones, and isoquinolinediones.

Abstract
A radical-initiated cascade addition and cyclization of N-allylbenzamides with simple ethers to construct ether-substituted dihydroisoquinolinones was performed in the presence of CuI. The cleavage of the sp3 C-H bond in ether and the sp2 C-H bond in phenyl was involved in this reaction. Moreover, the arylalkylation of N-allylanilines was also realized under similar reaction conditions, providing ether-functionalized indolines in good to moderate yields.
